ANDREW FREDERICK, OF HARMONY, PENNSYLVANIA.

TRACTOR.

To all whom it may concern Be it known that 1, ANDREW Fnnonni'cli, a.citizen of the United States, residing at Harmony, in the county ofButler and State of Pennsyl 'ania, have invented a new and usefulTractor, of which the following is a specification.

This invention relates to tractors and more particularly to a machine ofthis character having a single combined steering and propelling wheel,the said l'llilClllllC being, adapted to be coupled to plows, harrows,and other machines so as to draw them forward and being likewise adaptedto be fixedly connected to the front of any machine to be actuated so asto constitute practically an integral part thereof.

A furtluu object is to provide a machine of this character the motor ofwhich constitutes means both for actuating the pro pelling wheel and forsteering.

\Vith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the u-eciseembodiment of the invention herein disclosed, can be made within thescope of whatis claimed, without departing from the spirit of theinvention.

In the accon'lpanying drawings the pre ferred form of the invention. hasbeen shown.

In said drawings:Fig1ire .l is a plan view of the machine. F1 g. 2 is aview partly in section and partly in side elevation. Fig. 3 is a sectionon, line A-B Fig. .2, the drive shaft, its gear and SI'H'OClCOlL, and aportion of the wheel being shown in elevation. Fig. 4 is a plan view ofthe brake mechanism.

Referring to the figures by characters of reference 1 designates theside beams of the frame of the striuzture, said side beams havi'ngupwardly and inwardly converging portions 2 which, in turn, merge intoforwardly extending portions 3 secured in any suitable manner againstthe sides of a head. block 4:. An opening 5 extends through the headblock to receive the tubular stem 6 extending upwardly from the head 7of a yoke 8. This head is formed with a segmental gear 9 which mesheswith a worm 10 carried by a shaft 11. Said sl'iaft extends along oneside of the frame of the machine and preferably through one'of theupwardly extending por- Specification of Letters Batent.

tions 52, there being a sprocket 12 u on the rear end portion of theshaft and w ich receives motion, through a chain 13, from anothersprocket 14- secured to a shaft 15 extending horizontally, and mountedwithin suitable bearings. This shaftl5 has oppositcly disposed conicalfriction-gears 16 and a lever 17 is connected to the shaft andconstitutes means whereby the shaft can be shifted longitudinally so asto bring either of said friction gears into contact with a friction disk18 driven by the motor 19. A vertical shaft 20 is mounted upon the frameof the tractor and has oppositely disposed friction gears 21 arrangedabove and below shaft 15. A bell crank lever 22 is connected to theshaft and is adapted to be actuated by a link 23 extending to allover24. B

pulling the lever in one direction, the lint will shift the bell cranklever so as to move the shaft 20 upwardly whereas, when the lever 24- ismoved in the opposite direct-ion, shaft 20 will be caused to shiftdownwardly. Thus either of the gears 21. can be brought in contact withthe disk 18. Instead of raising and lowering shaft 20 by means of alever 30. When this lever is depressed, theband will be tightened on thewheel and the rotation of shaft 20 thus retarded or stopped.

Secured to the upper end of shaft 20 is a sprocket 31 adapted totransmit motion through a chain 32 to another sprocket 33 secured to theupper end of a shaft 34. This shaft is journaled within the tubular stem6 and extends downwardly to one side of a propelling wheel 35, therebeing a bracket 36 extending inwardly from on side of the yoke 8 and inwhich the lower end of shaft 34 is journaled. Pmpeiling wheel ispreferably provided with a broad tread and is connected to the yoke 8 byan axle 37. A large gear 33 is connected to or formed with one side ofthe wheel and is constantly in mesh with a small drive gear 39 securedto the lower end portion of the shaft'34. \Vheel 35 has radiallydisposed webs 40 constituting spokes and weights 41 are adapted, to beplaced within the wheelso as remake the wheel as heavy as desired. 1

A collar 42 may be secured to the stem 6 above the head block .4 andanti-friction de vices such as indicated at 43 may be inter-' posedbetween this collar and the head block and between the yoke 8.-

When. it is desired to use the machine as a tractor complete in vitself,supporting the head block and the top of Wheels 44 are connected a; therear portions of the side beams 1. Thus the machine can be used forpulling other machines. If desired, however, the side beams 1 can bebolted or otherwise secured directly to the machine :to be drawn and inthis event the wheels 44 are to be entirely removed.

By shifting one of the friction gears 21 into contact with the disk 18motion will be transmitted from said disk to theshaft 20 and throughsprocket 31, chain 32 and sprocket 33, to shaft 34. Gear 39 will thusactuate the large gear 38 and cause the Wheel 35 to rotate. By shiftingthe shaft 20 in the opposite'directi'on, the other gear 21 will bebrought 'into contact with the disk 18 and the movement of the machinereversed; Should it bedesired to steer the tractor, one at the gears 16is shifted into contact with the disk 18- and motion is thus transmittedfrom said disk and through the friction gear to the shaft 15 and thencethrough sprocket 14, chain 13 and sprocket provided upon theagricixltural machine, wagon or the like to be drawn by the tractor.

It is preferred to arrange two sprockets upon each shaft 20 and 34, onesprocket of each pair being larger than the other. In

the drawings a supplemental sprocket 45 has been shown mounted on theshaft 20 and another supplemental sprocket 46 has been shown mounted onthe shaft 34. Thus it will be seen that byv interchanging the sprocketsthe speed of the tractor can be va ried. The sprockets of each pair arepreferably formed in one piece.

Idler rollers 47 may be arranged under the chain 32 at any desiredpoints so as to prevent it from sagging.

A guard plate may, if desired, be secured to, the yoke S for the purposeof protecting gear 38. Thus the gear can be made much larger andtherefore brought nearer the ground, this consequently increasing thepower.

nstead of utilizing the friction gears 21, any other suitable powertransmitting means ma be used.

' \X hat is claimed is A tractor including a'fra'me, a motor supportedthereby, wheels for supporting'the frame close to the ground, said framehaving an upwardly extending end portion, a relatively large combinedpropelling and steer ing wheel arranged under and supporting -sa1dupwardly extending portion of the frame, a revoluble drive memberactuated by the motor, and separately operated means cooperating withsaid member for rotating the drive wheel-1n either direction and forsteering said wheel respectively.

In testimony that'l claim the] foregoing as my own, I have heretoaffixed my signature in the presence of two witnesses.
